TRAP ron Caron-Basins.

. Specification ofLetters.I'atent.

Be it knownthat I, FREn SGHULENBURQQ a oitizenof'thevUnited States,residing at River Forest, in the county of Gook'randf State ofIllinois-,have invented. certain new and useful. Improvements in Trapsfor: Catch Basins'; audit consists in certain peculiarities' of theconstruction, novel arrangement, and operation of the various; partsthereof, asfwill? be hereinafter more: fully "set forth and specificallyclaimed. As is well known tothose' skilled in theart 2 tozwhich myinvention pertains, every 'catchj basin in a sewage system is. equippedwith; atrap: at the point where the outletpipe of 1 the. catch-basin orsmallsewer-pipeleadingi to the main sewer, communicates-with thecatch-basin, and that these traps arealmost sary to clean or remove anobstructions, fronithe. outlet pipe Ofthe asin, and are: seldom if everrepaired or replaced, This: injury to and removal of theiold styletraps,

as well as, the neglect. to repair. or replacei them, causes insanitaryeonditions,'foul-and offensive odors and sickness. in the: locality ofthe basins.

ltzis the: principal object .of my invention to provide a trap forcatch-basins which shall be simple and inexpensive in construction,strong, durablevand eliicient in op eration, and so made,thatit can be.readily opened, without enteringzzthe basin, in order tOpGIIHit of theinsertion: ofa sewer-rod on other suitable implement into the outlet 1pipe of the basin,vfor unclogging or clearing the same, after which thetrap can be easily v closed, thus rendering it and the catch-basin aseffective andlsanitary as'originally, and without any expense for.repairs or. loss of time.

Other objects and: advantages of'thefiinvention willbe disclosed in thesubjoined' description and explanation.

Wall 15,

:Which byipreference is made mainly of brick :andii supported at -lts'lower portion on a horizontal: support 16', which may be a :woodeng ironaon'stone barextended segmentall'yacross 'th'e interior ofithe basin10', and supported at its ends. in or on the? walls zthereofiandra trap:orhorizontal wall 17 'which, as; is clearlyshownin' Figs.- 1 and 3 ofthe drawings, is located aboveithe upper :portion of thev innerendao-fztlre conduit .14, and closes th'e space between the-wallof thetrapz ndz the wall of thebasin at the up per. end of:saidispace; Theupper portion of the wall 15 is provided with 'arectangular recess 18,andthe central portion ofthe horizontal .wall or top; 1710f the trapislprovided with aacutout' portion 219, which com- ,municateswwith therecess 18; and: extends to the Wjall of- .the-basin' on each side ofthemiao ner end of the outlet or conduit, Located in the recess 18, andin the cut-out portion 19 aforesaid, is a block 20, which is angular Vkey-seat extends through the horizontal portion 23 of the block 20, andhas its Walls downwardly and inwardly inclined, aswill be clearlyunderstoodby reference to Figs. 4: and .5 of the drawings. Located inthe key-seat 21 is a key 24, which is preferably trapeziform, or may beOfOthQr shape to fit within a suitabl shapedkey-seat should the latterbe modi ed in form. Secured to the upper end of the key 24: is an eye or-staple'25, with which a rod having a hook on one of its ends can beengaged when it is desired to remove the key 24 from the seat 21, ortoplace the key in position in said seat. I

Should the outlet or conduit 14, leading from the catch-basin l0 tothemain sewer become clogged, or should it be necessary to clean the same,the key 24 may be removed from the key-seat of the block 20, by liftingthesaid key through the instrumentality of a hooked-rod or instrumentengaging the eye or staple 25, when it is apparent that the lower end ofthe guide 26, may be placed in the recess or key-seat 21 so as tooccupy.

about; the position shown by dotted lines in Fig. 2 of the drawings,when it is evident that a sewer-rod may be inserted through the guide 26into the outlet 14, for the purpose of removing the obstructiontherefrom, or forascertaining the location of said obstruction. In usingmy improved trap, it is manifest that as the support 16 for the lowerportion of the wall 15 of the trap is located ata distance from thebottom of the casing and that said wall islocated at a distance from thewall of the casing, space will be provided through which water may passfrom the basin out through the conduit 1& into the main sewer, but whenthe trap is closed by means of the key 24 oflensive odors will beprevented entering the basin or escaping from the same.

'By providing the vertical wall 15 and the covering 17 which constitutesthe trap, with the recess 18 and cut-out portion '19, respectively, itis apparent that the angular block 20, having the key-seat 21 and thekey Qlof a corresponding shape to fit said seat, which block and key maybe made of cement and carried in stock by dealers in plumbing or sewagesupplies, may be readily fitted for use in the said recess and cut-outportion of the trap, and that when it is neces sary to remove the key24'for the purpose of a cleaning the conduit, this can be readily doneby the means and in the manner above set forth. By this arrangement animproved article of manufacture, consisting of the block 20 and the key24: is afforded, and it is obvious that said members may be placed andfitted'in the recess and cut-out portion of'the trap by an ordinaryworkman after the trap has been built.

it will be seen that the recess 18 in the wall 15 of the trap has itslower portion located a considerable distance below the lower surface ofthe outlet conduit l l,'so that inthe event of said conduit becoming soclogged that the obstruction cannot be removed, by

removing the key 24 and inserting a sewer; rod through the opening inthe block 20 and I Furthermore, by referenceto Figs. 2 and 3 of thedrawings,

into the conduit, the'said block can be removed from the wall 15 andcovering 17 in order to enable a person to enter the catch basin andoperate with suitable instruments through the recess 18 to remove the0bthe operator more room to properly clean struction from the'conduit,thus affording f the conduit and trap than if the block 20,

with the comparatively small opening therein for the key, were in place.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent, is

1. The combination with a catch-basin, of

an outlet conduit leading from'the basin at a distance above the bottomthereof, a trap consisting of a vertical wall supported with in andonthe walls of the basin at a distance from the bottom of the basin and ata distance from the inner end of said conduit and having a rectangularopening in itsv a distance above the bottom thereof, a trap consistingof a vertical wall supported Within and on the walls of the basin at adistance,

from the bottom of the basin and at a distance from the inner end ofsaid conduit and having a downwardly extended opening 1 in its upperportion, a cover extended from the upper portion of said wall to thewall of the casing above the conduit and having an opening incommunication with the opening in said wall, a block having between itsside edges an opening provided with downwardly inclined walls and a keyremovably located in the last named opening and formed to fit the same.a l

3. The combination with a cylindrical catch basin, of an outlet conduitleading therefrom at a distance above its bottom, a segmental trapsupported within and on the wall of the basin with its lower edge at adistance from the bottom thereof and with its upper portion locatedabove the inner end conduit, and a downwardly tapered key re- 'movablylocated in said opening.
